The Effects of Sounds of Varying Intensities on Chickens and Hatching Eggs

摘要

Chickens grown under noise conditions from day old developed just as rapidly as chickens grown in control pens with a noise level of 65 decibels. There were no differences in growth rate, body weight.nSound levels in excess of 120 decibels had no effect on hatchability of hatching eggs stored prior to incubation in such a sound field. Likewise, sound had no apparent effect on hatchability when applied during incubation and hatching.
